摘　　要：以三聚氰胺、氯乙酸、稀土钇为原料,采用超声波法在水浴70℃条件下反应,制备三聚氰胺-N,N,N-三乙酸配体,再将制得的配体与稀土钇在50℃,pH=6.5条件下进行反应,制备三聚氰胺-N,N,N-三乙酸稀土钇配合物。对三聚氰胺、三聚氰胺-N,N,N-三乙酸配体及配体与稀土钇(Ⅲ)配合物进行溶解性测试;并用红外光谱对其分子结构进行表征。结果表明,三者的溶解性能极其相似;配合物形成过程中,配体分子中的—OH、—NH及C‖O同时与稀土钇(Ⅲ)离子有配位成键的信息。Melamine - N,N,N - triacetic acid - Y （ In ） complex was prepared by reaction of melamine - N, N,N - triacetic acid as ligand and yttrium using the ultrasonic method at 50 ℃ and pH 6.5 and characterized by IR spectrum. The melamine-N,N,N- triacetic acid was prepared by reaction of melamine, and chloro- acetic acid using the ultrasonic method in 70 ℃ waterbath. The solubility of melamine, melamine - N, N, N - triacetic acid, and melamine -N,N, N- triacetie acid -Y （ Ⅲ ） complex were also measured. The results showed that their solubilities were very similar. The information of coordination bonding of groups of -OH, -NH, and C=O with yttrium were observed.
